Ok I'm posting again, but with new thoughts. Having read through the text of the bill again I came up with this gem:

If Andy Taylor takes 12 year old Opie Taylor out to the woods to sight in his hunting rifle the week before Deer Season opens, Andy has to GIFT the rifle to Opie, who then owns the rifle- and can haul it all around Mayberry if he so desires. Luckily Mayberry is in North Carolina, which has no state minimum for possession of a long gun. Had Andy and Opie settled in Florida, poor Andy would have to choose between breaking the illegal transfer law, or the minimum age of possession State Law.
